Brodmann area 8 is one of Brodmann's cytologically defined regions of the brain. It is involved in planning complex movements.

In mammalian brain anatomy, the prefrontal cortex (PFC) covers the front part of the frontal lobe of the brain. It is the association cortex in the frontal lobe. This region is responsible for processing and adapting one's thinking in order to meet certain goals in different situations. These processes of thinking can include the brain allowing one to focus, control how they behave, and make different decisions.
The PFC contains the Brodmann areas BA8, BA9, BA10, BA11, BA12, BA13, BA14, BA24, BA25, BA32, BA44, BA45, BA46, and BA47.
The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. The DLPFC is not an anatomical structure, but rather a functional one. It lies in the middle frontal gyrus of humans (i.e., lateral part of Brodmann's area (BA) 9 and 46). In macaque monkeys, it is around the principal sulcus (i.e., in Brodmann's area 46). Other sources consider that DLPFC is attributed anatomically to BA 9 and 46 and BA 8, 9 and 10.
The DLPFC has connections with the orbitofrontal cortex, as well as the thalamus, parts of the basal ganglia (specifically, the dorsal caudate nucleus), the hippocampus, and primary and secondary association areas of neocortex (including posterior temporal, parietal, and occipital areas). The DLPFC is also the end point for the dorsal pathway (stream), which is concerned with how to interact with stimuli.
